I once attended coaching session in my basic schooling. At it, I learned of basic pattern in football play; dribble-tackle-pass and shoot. To knock off the pattern, I heard him tutor the team’s half-back [wing flank defenders] that they can technically retreat-offside-trap-if found themselves challenged at tackle but fullback [central defender] to be on hawked-eye at referee since this kind of technique depend on referee goodwill.
This what I saw Qatar team attempted to apply but paid dearly out of it in the first half.
